ntpwait - wait for ntpd to stabilize the system clock
ntpwait [-vV] [-n number] [-s secs]
The ntpwait program blocks until ntpd is in synchronized state. This can be useful at boot time, to delay the boot sequence until after "ntpd -g" has set the time.
ntpwait will do this quietly, unless the -v flag is provided.
-n number, --tries=number
The maximum number of times we will check ntpd to see if it has been able to synchronize and stabilize the system clock.
-s secs-between-tries, --sleep=secs-between-tries
We will sleep for secs-between-tries after each query of ntpd that returns "the time is not yet stable".
By default, ntpwait is silent. With this option, ntpwait will provide status information, including time to synchronization in seconds.
One of the following exit values will be returned:
